1. Introduction of Sucker rod
The Sucker rods are used to connect subsurface sucker rod pump and pump unite. We hold a international advanced upsetting production line with continuous upsetting in eight station, the rod connector has good forging structure and continuous metal streamline, which has high grain size and no overheating burnt, crack, pit, folding and other defects. Besides, it has good advantages of high accuracy forming, high liner degree, uniform organization performance, good corrosion resistance and stress rupture ability, which can preferably solve the problems of losing and unscrewing.
